Abstract

The present invention relates to a centralized water supply system of clean water. A running water processor which comprises a prefilter and an ultrafilter are communicated by a pipeline, and a water outlet of the running water processor is communicated with an elevated water storage tank by a main pipe. The top part of the sealed water storage tank is provided with an automatic exhaust valve which is connected with an air purifier, and a water outlet of the water storage tank is connected to branch pipes of all users, which are provided with valves, by main pipes. The present invention utilizes the height of storied buildings and the water sources of running water to realize limited concentrated water supply of clean water. The present invention has the advantages of low engineering cost and high clean water quantity. No power devices are arranged in the system, so noise is low.

Description

A kind of central water supply system that clean water is provided

The invention belongs to water system, particularly a kind of clean water central water supply system.

No matter city and rural area, provide industry and living water use mainly to rely on tap water supply system, and the drinking-water that the resident consumes only accounts for about 1% of total flow, because the limitation of pollution of waterhead and water treatment, tap water can not directly be drunk, handle if do the deep purifying of water in the water works, the sanitary standard that tap water is reached directly drink is non-remunerative naturally, even this processing mode is adopted in indivedual cities of extremely indivedual developed countries, do not have common and practical yet.The common mode that clean water is provided has with barreled or bottled sale and tap water terminal and installs water purifier additional, preceding a kind of mode is subjected to the restriction of supply channel and purchasing power and can not popularizes, a kind of mode in back exists the water purification degree of depth not enough, its reason is the restriction that is subjected to volume and manufacturing cost, so result of use can not be satisfactory.Utility model CN87216207 is a kind of inorganic nutrients water fountain, has embodied a concentrated reflection of the design feature of the home-use clarifier of this class, and promptly living water use and drinking water are selected control by the switch of this clarifier.

In common sanitary sewage recycling system, DE3738=231-A for example, the disclosed technical scheme of GB2249121-A foreign patent is that the sanitary sewage that collects in storage cistern is realized utilizing by the pressure that pump or inflation leather bag produce after simple filtration again.

The VS5303739A patent is an aircraft fresh water water system foreign patent, and it is the device that relies on pump, suction, pressure or gravity that the fresh water water storage tank is supplied water by the pipeline realization, and first water filling is inflated again in water tank, and house steward is provided with outlet valve.

The object of the invention provides a kind of central water supply system that clean water is registered one's residence of drawing that is different from above-mentioned clean water method of supplying.

Above-mentioned purpose is achieved through the following technical solutions the water treatment machine that gives filter (3) and ultrafilter (5) that comprises of connecting tap water with pipeline, its delivery port is connected the water storing tank (7) that places a high position by being responsible for (6), the automatic air valve (8) that is connected with air purifier (9) is equipped with at the tank body top of sealing, and the delivery port of water storing tank is through being responsible for the arm (12) that (6) connect the band valve (11) of respectively registering one's residence.

The water inlet of water storing tank (7) is located at the tank body bottom and is lower than delivery port;

Native system is furnished with electrical control cabinet (10); AC power connects control transformer (14) and air purifier (9) through earth leakage circuit-breaker (13), and the safe voltage of control transformer output is connected to blowdown electromagnetic valve (1), (4) of giving filter (3) and ultrafilter (5) respectively through the time relay (15), (16).

The present invention has following remarkable advantage:

1, make full use of the height and the tap water water source of residential building, office building, design limited clean water central water supply system, construction costs is lower, finally makes the clean water water rate cheap;

2, can adopt the large-scale water treatment machine of function admirable, the clean water quality is secure;

3, unpowered equipment in the system is convenient to realize operation low noise and unmanned.

Further specify the present invention with drawings and Examples below.

Accompanying drawing 1 native system is in esidential building building configuration schematic diagram

Accompanying drawing 2 electrical control cabinet electrical schematic diagrams

Attached explanation, electromagnetic valve 1,4, feed water valve 2 gives filter 3, and ultrafilter 5 is responsible for 6; water storing tank 7, automatic air valve 8, air purifier 9, electrical control cabinet 1D, valve 11; arm 12, earth leakage circuit-breaker 13, control transformer 14, the time relay 15,16, awning 17.

Embodiment is the clean water central water supply system configuration in nearly 80 apartment buildings, one 6 floor Building 4 as shown in Figure 1, normal day consumption clean water of estimation is 4000L, being equipped with 2 parallel capacity is 2000L stainless steel water jar (7), and the cover that automatic air valve (8) and air purifier (9) are housed is provided with conventional seal approach and fastening with tank body; Water treatment machine adopts the applicant to give filter and ultrafilter for what the hollow fiber filter membrane of designer's ZL94208335.0 patent and milipore filter were made, above-mentioned ultrafilter is by two single The parallel combined of holding in both hands, every handful day water yield ultrafilter is 10000L, giving filter is 20000L, so this water treatment machine gives filter by 1 and holds in both hands, 2 ultrafiltration are held in both hands and are constituted, and are enough to guarantee the clean water supply.Be responsible for (6) and arm (12) in the system and adopt 4/3 ", 2/1 " and 8/3 " stainless steel tube.

The course of work of native system is: open feed water valve (2) tap water and be treated as clean water through the ultrafilter (5) that gives filter (3) and two handful and connect, bacterium number index is less than 20/ml after tested, there are not Escherichia coli, be better than state-set standard, clean water flows into from the bottom of 2 water storing tanks (7) simultaneously by being responsible for (6), the design makes water flooding regime become muting immersion, when arm (12) no-output, the water storing tank water level of sealing rises rapidly, squeezing air discharges from automatic air valve, this valve model is selected the P711T-0.4 vertical automatic exhaust valve for use, when the water level rising is closed outlet valve automatically in the jar, hydraulic pressure equates to stop water filling inside and outside jar, during normal operation, each arm of registering one's residence will have clean water output at any time, water level must descend in jar, as long as automatic air valve is opened, the jar outer air enters in the jar through absorption type air purifier (9), clean water will be exported smoothly, and ultrafilter is gone into jar with moisturizing immediately simultaneously, and native system is non-stop run continuously under germ-free condition, the water storing tank of native system is located at roof, and require to put up awning (17), make the device in the system avoid exposing to the sun and rain, also be of value to preventing freeze in winter simultaneously.

The electrical control cabinet of native system (10), control transformer (14) is selected the BK-50 type for use, and time relay (15), (16) are selected the JS20-2/10-12 type for use, maximum 6 hours of controlled time, native system uses 2, the blowdown electromagnetic valve (1) (4) of filter and ultrafilter bottom is given in control respectively, and this valve model is DF-2-5, and the time relay of native system started once in per 4 hours, kept 30 seconds, to guarantee when the unmanned, realize regularly blowdown of water treatment machine, guarantee the clean water quality.
